The South Park boat ramp is a popular spot for launching boats onto the Snake River for some awesome water adventures. We like to put in here and then either float the river with tubes (can be cold) or paddleboard down the river. They sell tubes at Albertsons in town. There's a fun jumping rock near the bridge to stop and jump off, and some hot springs near the end. You'll take out at Astoria (Red Bridge) https://maps.app.goo.gl/ztV1fcBWKL5Mh3DB8.
